CONVERTIBLE BED AND SOFA OR CHAIR.

SPECIFICATION forming part of Letters Patent No. 737,743, datedSeptember 1, 1903.

Application filed October 27, 1902. Serial No. 128,995. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS KRAGEN, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inConvertible Beds and Sofas or Chairs and Hinges for the Same, of whichthe following is a specification.

My invention relates to improvements in convertible beds and sofas orchairs and in hinges for the same, and is an improvement upon theinvention for which a United States patent was granted to me September16, 1902,- No. 709,333.

The object of the present invention is to provide an improvedconstruction whereby,

the head-piece, which is folded against the lower portion of the back,is secured thereto, so as to permit of the adjoining edges of saidhead-piece and back being am ply upholstered or cushioned to form a softsupport for the head of the occupant of the bed and also to permit ofthe head-piece being folded snugly against the back of the sofa orchair, so that the latter can be moved close up to the wall.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side view of my improveddevice extended to form a bed. Fig. 2 is an enlarged side elevationshowing the head-piece folded over onto the top of the back,which isstill in a horizontal position. Fig. 3 is a side elevation of theapparatus when folded to form a sofa or chair, the rear edge of thesupport being broken away. Figs. at and 5 are enlarged perspective viewsfrom opposite sides of the hinge detached.

The apparatus described and illustrated herein is in the main identicalwith that described and shown in my patent above referred to, and theprincipal features thereof need not be specified in detail.

1 represents the box or support for the bed, to the front side of whichis hinged the seat 2, resting when the device is used as a bed upon thearms 3.

4 represents the back, hinged to the box or support 1, as shown in saidpatent, and having an extension 5 below said hinges. Said back when thedevice is to be used as a bed is swung forward, so that the upperportion rests upon the box 1, while the lower portion or extension 5projects rearwardly, forming the upper portion of the bed.

To the lower edge of the back is secured the head-piece 7, saidhead-piece being secured to said back by my improved hinges 8. Eachhinge comprises a leaf 9, secured to the frame of the back, a leaf 10,secured to the frame of the head-piece, and a link 11,jointed, as shownat 12 and 13, to said leaves. The link 11 has formed on its under side ashoulder lehabutting against a shoulder 15, formed on the leaf 9 andarresting the outward movement of the link when the link and leaf arealmost in a straight line. In like manner said link 12 and leaf 10 haveformed on their under sides abutting shoulders 16 and 17, which arrestthe downward movement of the upper leaf when said upper leaf and linkare in a straight line. The forward or inward movement of the linkrelatively to the lower leaf is arrested by means of a shoulder 18, castor formed upon the knuckle 19 of said link and overlapping the knuckle20 of the leaf 9, which shoulder abuts against the upper edge of theleaf and arrests the forward or inward movement of the link relative tothe leaf at an angle of about one hundred and thirty-five degrees. Theupper leaf is free to move forwardly to any desired extent, so that theupper edge of the head-piece can be brought down close to the surface ofthe mattress 21 which covers the back. When the head-piece is folded up,it is secured in place by any suitable means, as by a hook 22. It willbe seen that this construction per: mits of the head-piece and backbeing spaced apart at a considerable distance, so as to allow a thickmattress being interposed therebetween, while when the head-piece isopened out the edges of said mattress close to form a suitable cushionedsupport for the head of the occupant of the bed.

The knuckles 19 and 20 of the link and leaf are each formed of half thethickness of said link and the inner part of the leaf, so that theyoverlap one another, and when the link and leaves are put together thewhole hinge is of uniform thickness except at the terminalportions,which are madethinner tolighten the construction. Thisoverlapping of the knuckles permits of said knuckles being swung oneupon the other without requiring increased thickness of space in whichto work.

I claim A convertible bed, and sofa or chair comprising a suitablesupport, a back hinged to said support, a head-piece, and a hingeconnecting said head-piece and back, said hinge comprising leavesattached respectively to the head-piece and back and a'link pivotallyconnecting said leaves, said link and each leaf having coengagingknuckles of circular form moving in circular recesses formed by thecompanion knuckles and the parts to which they are attached, saidknuckles being placed side by side and having central pivot-pins LOUISKRAGEN;
